Customizing Your iOS Simulator Experience with Xcode Schemes
You can customize your iOS Simulator experience using the Xcode scheme editor. In fact, some iOS Simulator features are accessible only within this editor. The biggest advantage of using an Xcode Scheme is the ability to load application data files and routing app coverage files.
Click the scheme name in the scheme pop-up menu, and choose Edit Scheme.
When the Edit Scheme window opens, click the Run option in the scheme editor’s left pane.
In the main pane, click Options.
Specify the options you want.
iPhone Simulator Display. Specify the type of display your simulated iPhone will have (Retina or non-Retina).
iPad Simulator Display. Specify the type of display your simulated iPad will have (Retina or non-Retina).
Core Location. If you want to define the default Core Location setting, select Allow Location Simulation and choose a default location from the pop-up menu.
Application Data. If you want to load app data into the simulator, select the application data file from the pop-up menu. In this way, you can replicate the settings that were present when a problem occurred.
Routing App Coverage File. If your app uses routing, use this file to define the location boundaries in which your app will provide routes. For more information on routing app coverage files, see Location and Maps Programming Guide.
